TROL-LEY.

SPECIFICATION forming part of Letters Patent No. 553,410, dated January21, 1896.

Application filed June '7, 1895. Serial No. 551,936- (No model.)

To all whom, it may concern:

Be it known that 1, WILLIAM KA'UP, a citizen of the United States,residing at Newark, in the county of Essex and State of New J ersey,have invented certain new and useful Improvements in Trolleys; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawin gs, and to letters of reference marked thereon,which form a part of this specification.

The objects of this invention are to provide trolley-wheel guards, inconnection with reversible trolley-poles, of greater simplicity ofconstruction; to prevent interference of parts such as will derail thetrolley; to render the trolley-guard automatically adjustable inrelation to the pole, and to secure other advantages and results, someof which will be referred to hereinafter in connection with thedescription of the working parts.

The invention consists in the improved trolley-guard and in thearrangements and combinations of parts, all substantially as will be setforth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which similar letters ofreference indicate corresponding parts in each of the figures, Figure 1is a side elevation of a portion of the trolley in connection with thewire and having my improvements attached. Fig. 2 is a similar sideelevation showing the trolley in the act of passing a crossing wire.Fig. 3 is a front View of the same, and Fig. 4 is a sectional detailshowing the relation of certain of the parts more clearly.

In said drawings, a indicates an ordinary conducting-wire, and b atrolley-pole adapted to be arranged in connection with the car in anysuitable manner common in the art. 0 is a guide-rope which may beattached near the upper end of the pole, and d indicates thetrolley-wheel, which is peripherally grooved to receive theconducting-wire in the ordinary manner. The upper end of the pole b isprovided with a forked piece 1), between the ears or prongs of which isarranged the said wheel 61 on a pivotal pin a, Fig. 4, the ends of whichextend beyond the outer faces of the said prongsand serve as pivotalbearings for leverlike guard-carriers f, which are held on said pivot bywashers g and screws h,as indicated in Fig. 4. -Said guard-carriersproject from their pivotal or fulcrumal bearings beyond the extremitiesof the prongs, and their projecting ends provide pivotal bearings forthe guards i. The said guard-carriers are held normally in thelongitudinal center-line of the trolley-pole by springs j, but areallowed a limited play by said springs. At the upper projecting ends ofsaid carriers, adjacent to the pivotal bearings of the guards, the sameare flanged or broadened and at the outer extremities are provided withsegmental slots or recesses k. Within the said recesses are disposedprojecting pins or lugs Z, which extend from the outer sides of theguards into said recesses, and the said guards are thereby allowedlimited movements on their axial centers, for the purposes hereinafterreferred to. The said guards are arranged to lie on opposite sides ofthe conducting-wire a and thus serve to prevent disconnection of thetrolley by lateral movement should the trolley-wheel jump the wire. Theyare shaped so as to present to the crossing wires, in both forward andbackward movements of the car, inclined surfaces by means of which thepressure of the said crossing wire will be brought gradually upon theguards to repress the same, as indicated in Fig. 2, and thus admit of apassage of the said guards thereunder.

The shape of the guards may be varied to some degree, but that preferredis shown in Figs. 1 and 2, where m m are the forward inclines adapted toengage the crossing wires in the forward movement of the car, and n nare rearward inclines adapted to engage the said wire when the carcrosses the same in a backing movement. As the trolley-pole is changedin position of inclination to secure the reverse movements of the car,the pivoted guards c' 'i being free to move on the pivot e, gravitatewith a movement independent of the carriers f until stopped by the pinsZ, engaging the end abutments or shoulders of the slot or recess 70, theguards thus automatically adjusting themselves to the new position ofthe trolley, so that the inclines m n will be brought into properrelation to the cross-' ing wires to secure the desired depression,either in the forward or rearward movement of the. car beneath thecrossing wire. Upon engagement of the crossing wire with the inclinedsurfaces of the guards the latter are forced downward with the carriersf, the latter turning on their fulcrumal centers to admit such movement.

Having thus described the invention, what I claim as new is 1. Thecombination with the trolley pole and wheel, (1, of guard-carryinglevers arranged on opposite sides of said wheel, springs holding saidlevers in normal position and guards pivoted on said levers and free togravitate a limited distance when the trolley pole is reversed,substantially as set forth.

2. The combination with the trolley pole and wheel, of a springcontrolled guard-carrier, and guards having opposite inclines,

m, m, and n, n, and pivoted on said carriers, substantially as setforth.

3. The combination with the trolley pole and wheel, of a springcontrolled guard carrier, pivoted guards, each having a limiting pin orlug, l, and opposite inclines, m, m, and n, n, all arranged andoperating, substantially as set forth.

4. The combination with the trolley pole and wheel, of a springcontrolled guard recessed at its outer end, pivoted guards havinglimiting lugs or pins in the recesses of said guards and having oppositeinclines, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this31st day of May, 1895.
